If you own a 2016 Cadillac CTS, knowing the lug nut size is important for changing a tire or swapping out wheels. The lug nuts help secure the wheels to the vehicle’s hub assembly. Using the wrong size lug nut can damage the wheel or result in a wheel coming loose. So what size lug nuts does your CTS need?

OEM Lug Nut Size for 2016 Cadillac CTS

The factory lug nuts on a 2016 CTS are M14 x 1.5. This refers to the thread pitch and diameter in millimeters. Specifically:

  • M = Metric thread
  • 14 = 14 mm diameter
  • 1.5 = 1.5 mm between threads

So a proper socket or lug wrench is needed to remove or install the OEM Cadillac lug nuts. Most sockets come in standard and metric sizes.

Double check your owner’s manual or door jamb sticker to confirm the lug nut size. But M14 x 1.5 is standard for all 2016 to 2023 model year CTS vehicles.
